Abstract

The invention discloses a antimony germanate glass and a preparation method thereof, belonging to the field of optical materials. The composition and ratio of the antimony germanate glass are: 5-95 mol% GeO 2 , 5~95 mol% Sb 2 o 3 And 0~55 mol% BaO. The antimony germanate glass of the present invention has the advantages of large glass forming area, good glass forming performance, adjustable properties, low phonon energy, wide infrared transmission range and good thermal stability, and is an excellent near-middle infrared multiple Component laser glass and glass fiber matrix materials can be applied to the core gain medium of high-power single-frequency fiber lasers.

Description

technical field [0001] The present invention relates to the field of fiber laser materials, in particular to antimony germanate glass with large glass forming area, good glass forming performance, adjustable properties, low phonon energy, wide infrared transmission range and good thermal stability and its preparation method. Background technique [0002] Fiber lasers occupy an important position in the fields of optical fiber communication, optical fiber sensing, precision processing, medical surgery, etc. and rapidly expand to other broader laser application fields, bringing profound changes to modern human life and production practices. Laser glass is the core gain medium of fiber lasers, which consists of matrix glass and active ions. The physical and chemical properties of laser glass are mainly determined by the matrix glass, and the matrix glass has an important influence on the spectral properties of the activated ions. Therefore, choosing a suitable matrix glass sy...
